TROLLEY-WIRE HANGER.

Specification of Letters Patent.

Patented July 4., 1916.

Application filed October 22, 1914. Serial No. 867,982.

citizen of the United States, residing at- Mansfield, in the county of Richland and State of Ohio, have invented a certain new and useful Improvement in Trolley-Wire Hangers, of which the'following is a specification.

My invention relates to improvements in trolly wire hangers used for suspending or hanging a trolley wire from a cross or span wire or support, and one of the objects of my invention is to provide an improved device of this character which will be simple, durable and reliable in construction, and effective and eflicient in. operation.

Other objects of my invention will appear hereinafter. 1

Referring to the accompanying drawings: Figure 1 is a view in elevation of the several parts of my improved hanger, ready to.be assembled. Fig. 2 is a top'plan view ofsuch parts in their assembled operative relation, and Fig. 3 is a central sectional view of said hanger, showing it in operative relation to a cross suspension wire and a trolley wire.

My improved hanger is intended more particularly, though not necessarily,

the usual cross susoverhead system from In the construction pension or span wires.

shown in the drawings, I provide prefera flat band ring or annulus of metal A,,

hooks are preferably disposed above the plane of the upper edge of the supporting ring A and are so arranged that they aline diametrically with respect to the ring itself. These hooks are adapted to be hooked over the cross or suspension wire, represented in Fig. 3, as D, so as to support the hanger in po- 55. taper of the wall sition on said cross or span wire D. The wall of the supporting ring A is tapered in such a way that these Walls diverge upwardly. This construction is provided so that the ring will form a seat and also a supporting member for a block or body of insulating material E, such as porcelain or the like.

The periphery F of this body of insulating material is tapered corresponding to the of the ring A, so that the to be used for suspending a trolley wire in an 'K of the hanger it will body of insulating material will be positioned and held firmly within said ring. In this manner not separate fastening means is required for holding the ring and insulatlng material in their assembled relation and at the same time the insulator F may be readily removed from or placed Within the ring A. It also may be readily rotated with respect to said ring while in position there in. The insulator E is preferably round or ,convex on its upper side and rises somewhat above the upper edge of the ring A. The lower side ofthe insulator,however, lies entirely within the ring A, that is to say, the ring A extends somewhat below-the lane of the bottom side or face of said insu ator, as indicated at G in Fig. 3, so that the ring A completely protects the insulator from being struck and thereby damaged by the trolley Wheel on the car in the event that said trolley Wheel leaves the wire.

The under side or face of the insulator E -has a central depression or socket, the wall of which preferably has a series of grooves H. A stud member J isset in the socketin said insulator and preferably has a series of corresponding grooves, and the grooves the insulator and stud member J and the space therebetween in the socket are filled up with cement or other substance for firmly securing said stud member in position. The stud member J has a threaded portion K depending below the insulator and ring. This threaded portion forms a suitable means for attaching the trolley ear L to the hanger. In the drawing I have shown in section one formof trolley ear L suitable for this purpose, but this maybe regarded as representative of any of the .standard or desired forms of trolley ears. This ear is shown as being attached to the trolley wire M. In overhead systems the-cross or span Wire occupies an angular relation with respect to the trolley wire. This angle varies, of course, in accordance with the particular conditions, but it is generally that of a right angle. .In the ordinary forms of hangers it frequently happens that after the trolley ear L has been tightly screwed onto the stud not occupy the proper angular position with respect to the cross or span wire. In such a case the trolley ear must be turned by force upon the stud until it does occupy the proper angular position,.or else it Is not screwed quite home, and is left loose on the stud. Both of these conditions are Obviously undesirable. With my improved hanger it will be seen that the trolley ear L can always be screwed onto the stud until it is tightly fastened. The insulator E may then be rotated within the ring A until the trolley ear is positioned at the proper angle with respect to the cross wire D, thus rendering the hanger readily adaptable to the various conditions found in practice. The upper convex surface of the insulator E is provided with a number of grooves N across its top. These grooves are preferably two in number and placed at right angles with respect to each other, so that either one of them may be lined up with the supporting hooks C, thus providing a seat, in said insulator for a cross or span wire D. In this manner it will be seen that the supporting ring A and the insulator E are not only locked together by the cross wire D, but they are also prevented from relative rotation with respect to each other after they have been once assembled. In

order to allow for inaccuraciesiof manufacture and also to provide a comparatively soft resting surface for the insulator E I sometimes interpose a tapered gasket or ring 0' between the insulator E and the ring A. This gasket is preferably of soft metal, such as lead or copper, and will adjust itself or yield to the irregularities in the ring'and insulator E. The under surface of the insulator E may, if desired, be provided with a number of concentric ribs or petticoats P so as to increase the leakage surface between the central stud and the ring A.

I claim:

1. In a trolley wire hanger, the combination with a metal ring having an inwardly inclined seat and diametric extending hooks, of an insulator fitting within the ring having a convexly rounded top with a plurality ing threaded stem, a trolley wire ear thread-- ed on the stem and moved tightly against the stud, and a suspension wire for the hanger which passes under the ear and is seated in a diametric groove for holding the insulator in the ring and adjustable for different grooves to change the angular position of the insulator so that the said trolley ear will be in proper alinement.

2. A trolley wire hanger comprising a metal ring inclined inwardly at the bottom and extending hooks at the opposite sides, an insulator having a bottom aperture and a convexly rounded top with a plurality of diametrically extending grooves at angles to each other and inclined sides so that the insulator may be fitted loosely and adjusted in the ring, a stud rigidly fixed in the said bottom opening of the insulator having an extending threaded stem, a trolley wire ear threaded on the said stem and threaded tightly against the stud, and a suspension wire extending under the said hooks and over the convex top of the insulator in one of the said diametric grooves for holding the insulator firmly in the said ring, the insulator being rotatable before the wire is applied to place the said trolley ear inany desired alinement, and the said wire being then seated in the corresponding groove in the top of the insulator for holding the insulator in place.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 9th day of October A. D. 1914.
